To all whom t may con/cern.-

Be it known that I, SAMUEL R. BAILEY, a citizen of theUnited States, and a resident of Amesbury, in the county of Essex andA State of Massachusetts, have invented certain new and useful Improvements in Shaft-Shackles for Vehicles, of which the following is a speciiication. A

This invention relates to improvements in shaft-shackles for vehicles, and has for its ob- `ject a devioe'of improved and simplified construction capable of being readily applied to and detached from the clip.

My invention consists in the features and in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claims following thedescription, reference being` had to the accompanying drawings, forming a part ofthe specification wherein;- l

Figure l is a front elevation of'my improved shaft-shackle, showing the same applied to a thill-coupling of a vehicle-axle. Fig. 2 is a longitudinal section on the line 2 2 shown in Fig. l. Fig. 3 isra detail front elevation of the inner` end of the shaft-iron.

Fig. 4 is a cross-section on 'the line 4 4 shownv in Fig. 2; and Fig. 5 is a detail rear view of the adjustable jaw, shown as removed from the shaft-iron.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

Referring to the drawings, indicates one end of a carriage thill or shaft secured in a suitable :manner to the shaft-iron B.

The shaft-iron B is provided at its rear or inner end with a preferably semicircnlar jaw ZJ, which in connection with 'an adjustable pivoted preferably semicircular jaw C is adapted to encompass the thill-coupling bolt D or an elastic sleeve d, located thereon, as shown.

The bolt D is pivotally connected to the ears E E of the clip E', which is secured to the carriage-axle F by means of the plate G and nuts e e, as is common in devices of this kind.

The rear inner face of the thill-iron B is provided with a cylindrical recess b', and from the central bottom portion of Such recess projects an externally-threadedstud or l screw b", which may be formed,l preferably, integral with the thill-iron B, as shown, or may be attached .thereto in any desired or suitable manner.

The adjustable jaw C is provided at its inner end with a sleeve C', which is guided and `longitudinally adjustable in the cylindricalrecess b in the shaft-iron B, as shown.

Within said sleeve C' is journaled a cylindrical `nut H, which is internally screw` threaded, so as to engage the correspondinglythreaded screw-bolt b", as shown in Figs. 2 and 4. To the ,outer end of the internallyscrew-threaded'nut or sleeve H is secured in a suitable manner an actuator H', preferably made in the form of a circular Wheel or disk;

tion of saidactuator or adjuster, as it may be made in the form ofj'a lever or, thumbpieceof any desired shape Without departing from the essence of myinvention. In practice I prefer to provide such actuator or lever with one or more perforations h h h,

nectedto the thill-coupling plate G by passing it through a slotted perforation g in the latter, asshown in Fig. 2, which strap serves, when connected to the` plate G and adjuster H', as a means to` prevent the latter from rotation. rotated in the Sleeve C inthe adjustable jaw C, but is prevented from having any `longinut, adjacent tothe inner end of the sleeve C' on'the jaw C, as'shown in Figs. 2 and 4. The outer endof the sleeve C is held in contact with the under` side of the adjusterV or actuator H'. Consequently the jaw C and its sleeve C' are caused to moved in and ont rel.

the rotary adjustment of the actuator or lever H', as shown in Figs. 2 and 4.

To couple the thill to the bolt of the axleclip, it is only necessary to place the'jaw b over the thillcoupling bolt or its rubber sleeve and then turn the jaw C upon the sleeve C' as a pivot until it alines with the jaw b. The nut H is then screwed Aon the screwf threaded bolt b" by turning the actuator I-l' ative to the shaft-iron B andits jaw b during but I wish to state that I do. not desire to y adapted to receivea strap l, preferably con- The cylindrical nut H may be freely l tudinal motion therein`- by means of an upset or Washer 72,', located at the inner end of said until the jaws C and b encompassthe clipclogging of the parts are prevented.' The screw of the adjusting device is not'liable to bend or bind on account of the sleeve on the adjustable jaw being guided in a socket or recess in theshaft-iron. By having the adjuster provided with one or more apertures adapted to'be connected to the thill-coupling or shaft by means of a strap the adjuster yis prevented from turning loose, thus preventing the spreading of the jaws in which the thillcoupling bolt is journaled'. By means of said screw-actuated adjuster the movablejaw may be closed relative to the lower jaw and the,

coupling-bolt or its rubber sleeve with just as little force as necessary for accomplishing the 1 desired result.

Having thus fully described the natnre,con struction, andr operation of my invention, I wish to secure by Letters Patent and claim- `l. In a shaft-shackle, the combination with 4the thill-iron terminatingl at its extremity in a jaw b, and provided on its inner face with a threaded stud b, of the interiorly-threaded sleeve I-I, engaging said stud and provided with an adjuster, and the jaw C, journaled on said sleeve and provided with an extremity adapted to encompass the bolt D, or its elastic cushion d, as set forth. 'f

` 2.' In a shaft-shackle, the combination with the thill-iron terminating at its extremity in a jawy and recessed on its inner face, at b', of a threaded stud b, projecting from said recessed face, the interiorly-threadedsleeve H,

engaging said stud and provided with an adjuster, and the jaw C,journaled on said sleeve, and provided with an .extremity adapted to encompass the boltD, or its `elastic cushion d, as set forth. v

3. In a Shaftshaekle, the combination with the thill-iron terminating at its extremity in' a jaw b, and recessed on its inner face at b', of a threaded stud b, projecting from said recessedface, the interiorly-threaded sleeve H, engaging said stud and provided with anadjuster H', and means for connectingithe latter to the shaft or vthill-conpling and the jaw C, journaledon thesleeve H, adapted to encompass the bolt D, or its cushion d, asset forth. v

In testimony whereof I have affixed my signature in presence of two Witnesses.'
